Organic (non certified), gourmet mushroom spawn ready to be mixed into substrate for fruiting. Both oyster strains produce beautiful, large mushrooms! Priced by the kg.


Beginners / first time growers please start with our 5 Step Box! After that you will have a good understanding of what spawn is and how to use it.


All spawn is organic grain/sawdust and is only shipped once we're sure it's contaminant free.

If you notice any color other than white in the bag upon arrival please email us a photo before opening. If contaminated, we will replace it! Sawdust and dowel spawn are also available for purchase.


All spawn and culture work is done inhouse in our own labatory.


Spawn will be sent in a 0.2 micron filter patch bag.


Delivery may be up to 1-4 weeks depending on supply. We will let you know a time frame at time of purchase if it is going to be longer. Oyster and shiitake spawn can usually be shipped within 1-2 weeks.


Often spawn is confused with 'mushroom spores.' We use spawn from our selected cultures as we know exactly how they will produce and are suited to NZ conditions. Using 'spores' results in random variations of production and yield, sometimes not producing mushrooms at all.
